I'm using urlRewrite for friendly urls. This works great! However, whenever I log-in, the page refreshes and the url changed back to un-friendly url. E.g. the friendly url is http://domainname.com/about_us. Upon logging in, the page refreshes and the url changed to http;//domainname.com?page=about. I want the url to stay same whenever I log in. How can I do that?
